Hi, such in your example as visual artists; composers also can draw their inspiration from everyday life. For a film composer a scene can be a starting point. Everything has a rhythm and tempo to begin with. Most composers find their chord progressions first and the movement of these chord patterns start suggesting melodic themes. Other times could be the opposite as well. Melodic ideas possibly need harmony and that can be the 2nd stage as the chords following the melody.
